These are VST2 and AAX plugins
for macOS (10.7+) or Windows
(Win7+) running on 32bit/64bit Intel. They can be hosted in some Digital
Audio Workstations (DAWs) that can handle tracks with sufficiently high channel counts.
Options include Reaper,
Pro Tools HD,
Pyramix and Max/MSP. Not all plugins are supported in AAX.

We use some free software and data in this
product. Before purchase, please check the
license agreement.
Prices include VAT where applicable. EU VAT is normally
charged at your local rate using the MOSS VAT system, but please get
in touch before purchase if you need a business-to-business transaction.

Highlights

What Does This Do?

These plugins take multichannel mixes (such as 5.1) and convert them to stereo designed to be played in 3D on headphones. The sound is processed with "HRTF" data to make a binaural recording, so that sounds can be heard in 3D.

Generally, the output sounds natural on speakers, although the 3D effect is lessened. It can be strengthened through use of our Stereo Crosstalk Cancellation plugin in some circumstances.

The processing uses our Amber HRTF technology. It uses our Higher Order Ambisonic (HOA) technology internally, but you don't need to think about that while using it.

Processing

There are two modes supported. In "Virtual" mode, each channel is
panned into place. Alternatively, "Inferred" mode uses a patented
technique to help fill in the gaps between speakers.

Either way, we use passive processing techniques, so we don't
mess with the character of the sound. You won't hear any DFT
processing artefacts. Instead, the image produced is spacious and natural.

Making Great Binaural Mixes

Much as we'd hate to discourage you from buying one of our products,
these plugins are not generally the best way to make
great-sounding binaural mixes with our tools!

These plugins are designed to work with material that is already
in legacy surround formats like 5.1. However, if you are starting from scratch, better
results can be achieved using our Third Order Ambisonic (O3A) plugins. Working
this way, you can build up a complete 3D audio scene using our free
O3A Core plugins and others O3A plugins from
our pro audio range.

If you are working with Virtual Reality, a O3A mix can be used directly with the new
Rapture3D game/VR engine, and respond to head-tracking. Alternatively, if you want
to decode to binaural stereo in the studio, the best option is often the
"O3A Decoder - Headphones" plugin from the O3A
Decoding pack, although Rapture3D
Advanced can be used too. It is also possible to decode to 5.1 and many other
formats.

Even if you do have legacy surround material you want to use, you
could still take the O3A path via the O3A
Upmixers pack. This is more complicated of course, and requires a DAW that
can handle the O3A channel requirements.

However, if you neither need nor want to use ambisonics,
the Binaural Surround plugins might be right for you after all!

Plugin List

Binaural Surround - 5.1

I/O: 6 in, 2 out

This plugin converts 5.1 into a 2D binaural headphone mix.

Binaural Surround - 6.1

I/O: 7 in, 2 out

This plugin converts 6.1 into a 2D binaural headphone mix.

Binaural Surround - 7.1

I/O: 8 in, 2 out

This plugin converts 7.1 into a 2D binaural headphone mix.

Binaural Surround - 7.1.2

I/O: 10 in, 2 out

This plugin converts 7.1.2 into a 2D binaural headphone mix.

Please note that this is not a Dolby Atmos renderer.

Binaural Surround - Auro-3D 9.1, 10.1, 11.1 and 13.1

I/O: 10, 11, 12 or 14 in, 2 out

AAX: only 9.1 supported, mapped to 7.1.2

This plugin converts Auro-3D into a 3D binaural headphone mix.

Note the number of channels that need to be input to this plugin. The plugin does not unpack compressed Auro-3D audio.

Binaural Surround - 22.2

I/O: 24 in, 2 out

AAX: not supported

This plugin converts 22.2 into a 3D binaural headphone mix.

Please note the huge input channel requirement here.

Stereo Crosstalk Cancellation

I/O: 2 in, 2 out

This plugin reduces stereo crosstalk at a (rather small) sweet spot to increase the perceived stereo width there. This can produce a surprisingly wide stereo image from stereo speakers.

Tech Requirements

Operating System

Supported versions of Microsoft Windows are Windows 7, Windows 8 and Windows 10. Supported versions of Apple macOS are 10.7 or later, Intel only. The VST plugins are available in 32bit or 64bit forms on both platforms (packaged as a Universal Binary on macOS). The AAX plugins are 64bit only.

VST Host

The VST plugins require a VST 2 host.

These plugins do not work with all VST 2 hosts. They are multichannel plugins and so will not work on VST hosts that only handle stereo. Also, note that some of the plugins need large numbers of channels on each track. For instance, the "Binaural Surround - 22.2" plugin needs 24 channels of input. Check the individual plugins for the channel counts they need.

AAX Host

The AAX plugins require Pro Tools HD v12.8.2 or later.

Due to channel and stem restrictions, not all plugins are supported in AAX. Please see the documentation for details.

PC Hardware

Please check your PC meets the following requirements:

Intel Pentium D CPU or better.

200MB of free disk space.

Internal network card.

Internet Connection Required

These plugins require an Internet Connection for license activation and verification. We don't really like this, but we can't think of a better way to discourage piracy! Please don't hack our code, it's taken a lot of effort to get it this far...

Successful license verification isn't required every time you use the software, but it is needed during installation and needs to succeed once every couple of weeks to keep the license fresh.

The license can be "revoked" to remove it from one machine so it can be moved on to another. You should also do this if you're updating your system in case the machine appears to have changed identity.
